I have 2 macs and i'm trying to sync up the desktop backgrounds via iDisk. Unfortunately, the iDisk doesn't mount immediately so OSX goes back to the default background. In leopard just opening up system preferences to the desktop and screen savers pane fixed the problem, but that fix doesn't work in snow leopard. I had this script in Leopard: tell application "System Preferences" activate set current pane to pane "com.apple.preference.desktopscreeneffect" quit end tell If i toggle the "Change Picture" checkbox off and then back on, it solves the problem. so i need a script for this, and i don't know what i'm doing.
